The gang over at Good Old Games has sent word that Moebius, the new adventure game by Jane Jensen, is now available for preorder with a 20% off price tag, a free soundtrack and a GOG.com exclusive demo.

For those that are unfamiliar with the title, here's a brief description to accompany the above pre-order trailer:

Moebius is a contemporary metaphysical adventure from Jane Jensen, the creator of Gabriel Knight and Grey Matter, with a mixture of 2D and 3D graphics, immersive soundtrack, and psychologically rich characters. The protagonist's unique ability to transform people and clues into interactive puzzles introduces a new approach to merging point-and-click gameplay with sophisticated storytelling.

So, as I said, the game is available for preorder on GOG.com for Windows and Mac OS X 20% off ($23.99) and compltely DRM-free, with free soundtrack and GOG.com-exclusive demo, covering the first two chapters of the game. The offer lasts until the game's release on April 15. If you're interested, head here.
